Top Dem: Obama 'Too Cautious' In Confronting ISIS (VIDEO)

Sen. Dianne Feinstein (D-CA) on Sunday said that President Obama has not been aggressive enough in his approach to ISIS, which is gaining power in Iraq and Syria.

"I’ve learned one thing about this president, and that is he’s very cautious— maybe in this instance too cautious," Feinstein said during an interview on NBC's "Meet the Press."

Feinstein, the chair of the Senate Intelligence Committee, said that the ISIS threat to the U.S. is "potentially very serious."

“This is a vicious, vicious movement, and it has to be confronted," she said.

According to Feinstein, ISIS could pose a direct threat to Americans.

“I believe it is on its way to Baghdad, and I believe they will try to attack our embassy from the West," she said.

The senator said that she agrees with conservative Sen. John McCain (R-AZ) and Sen. Lindsey Graham (R-SC), who co-wrote an op-ed in the New York Times urging the president to act quickly in confronting ISIS.

While she was largely critical of Obama's approach, she said he is right to push for a new Iraqi government that could rally Sunnis to push back against ISIS.
